BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is directed to methods for treating livestock or poultry confinement facilities equipped with manure collection zones, such as pits or litter accumulations, to reduce and mitigate the effects of gaseous ammonia within the facility and thereby lessen the deleterious effects of ammonia on the livestock or poultry within the facility. More particularly, the invention is concerned with such methods wherein an aqueous treatment material comprising a partial calcium salt of a maleic-itaconic copolymer in combination with a partial ammonium salt of a maleic-itaconic copolymer. Such treatments promptly reduce the gaseous nitrogen content within the confinement facilities, and maintain such reductions over a significant period of time.
Description of the Prior Art
Ammonia is a common by-product of animal waste due to the often inefficient conversion of feed nitrogen into animal product. Livestock and poultry are often fed high-protein diets, which contain surplus nitrogen in order to assure that the animals' nutritional requirements are met. Nitrogen that is not metabolized into animal protein is secreted in the urine and feces of livestock and poultry, where further microbial action release ammonia into the air during manure decomposition.
Ammonia is typically considered an indoor air quality concern by poultry and livestock producers, because the gas accumulates inside poorly ventilated and/or managed animal confinement facilities. Elevated levels of nitrogen can have a negative impact on animal health and production, resulting in increased susceptibility of birds to bacterial respiratory infection, and decreased weight gains, feed conversions. Similarly, other livestock suffer under elevated ammonia conditions within a confinement facility.
Producers have adopted a number of strategies to lessen ammonia levels within confinement facilities, especially in cases of poultry coops or houses. Thus, it is known that a variety of amendments including aluminum sulfate (alum), ferrous sulfate, phosphoric acid, and other proprietary products may be sprayed or otherwise applied to the poultry litter. In the case of manure pits beneath livestock barns or houses, producers have principally relied upon ventilation to reduce ammonia levels. However, these methods have not completely solved the ammonia problems inherent in animal confinement facilities.
Specialty Fertilizer Products, LLC, of Leawood, Kans. (SFP), has heretofore commercialized a series of maleic-itaconic copolymers principally for use with solid or liquid ammoniacal or phosphate fertilizers, such as urea or UAN fertilizers, in order to significantly increase the performance of the fertilizers as evidenced by increased yields.
These prior products include Nutrisphere-N® for Liquid Nitrogen Fertilizers, which is a partial calcium salt of a maleic-itaconic copolymer in water with a solids content of at least 30% w/w, and more preferably about 40% w/w. The copolymer is formulated using equimolar amounts of maleic and itaconic moieties. The final product has a pH of 1-2 and is a light brown to yellow viscous liquid.
Another such product is AVAIL® for Liquid Phosphate Fertilizers is a partial ammonium salt of a maleic-itaconic copolymer in water with a solids content of at least 30% w/w, and more preferably about 40% w/w. The copolymer is formulated using equimolar amounts of maleic and itaconic moieties. The final product has a pH of about 2 and is also a light brown to yellow viscous liquid.
SFP has also previously commercialized a manure nutrient manager product under the trademarks More Than Manure® or MTM®, which is primarily designed to reduce phosphorous lock-up and nitrogen loss when applied to manure in an open-air pit or lagoon, or directly onto litter after field application of the litter. MTM® is an aqueous mixture made up of two-thirds by volume Nutrisphere-N® for Liquid Nitrogen Fertilizers and one-third by volume of AVAIL® for Liquid Phosphate Fertilizers, having a solids content of from about 30-60% w/w, a pH of about 3 and a specific gravity of from about 1.1-1.4. Other benefits of the MTM® product include increased crop rotation flexibility, biodegradability, and reduction of manure solids. In such prior uses of MTM®, no odor-reduction studies were conducted, but numerous MTM® users expressed the opinion of a notable reduction of odor from the use of the product.
SUMMARY OF THE INVENTION
It has now been discovered that gaseous nitrogen levels in livestock and poultry confinement facilities can be promptly and significantly reduced for marked time periods by applying an effective amount of a treatment composition to manure within or directly below the facility. Such animal or poultry confinement facilities include upright walls forming an enclosure, a manure collection zone within or below the enclosure, and a roof substantially covering the zone. Examples of such facilities are dairy and hog farrowing, finishing, and calving barns, and poultry coops, barns, and houses. In some instances, the facilities include a manure pit directly below the roof and enclosure, while in others the facilities have a floor covered in litter, which is mixed with animal manures. Usually, the liquid material is applied directly to manure within a pit by simply pouring the product into the manure mass. In the case of litter/manure mixtures, the product is normally sprayed onto the mixture.
The treatment material comprises an aqueous mixture including a partial calcium salt of a maleic-itaconic copolymer and a partial ammonium salt of a maleic-itaconic copolymer. The product typically has a pH of from about 1-5, more preferably from about 2-4. Actual test results confirm very significant reductions in gaseous ammonia within treated livestock or poultry confinement facilities, with a single application lasting for several weeks.
The fact that the treating materials methods of the invention can reduce ammonia levels withing confinement facilities so rapidly and effectively is quite surprising, because no known prior treatment can achieve such results.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The Partial Salt Maleic-Itaconic Copolymers and the Treating Materials
The preferred maleic-itaconic copolymers useful in the invention are described in U.S. Pat. Nos. 6,515,090 and 8,043,995 fully and completely incorporated by reference herein. In general, the copolymer salts should each desirably contain from about 10-90% by weight maleic moieties (more preferably from about 25-75% by weight), and correspondingly from about 90-10% by weight itaconic moieties (more preferably from about 75-25% by weight). Overall, each of the copolymer salts should include at least about 85% by weight of maleic and itaconic moieties, and more preferably at least about 93% by weight. Accordingly, the copolymer salts may also contain other moieties apart from maleic and itaconic moieties, such as vinyl moieties. However, such other moieties should be present only up to a level of about 15% by weight, more preferably up to about 7% by weight. Preferably, each of the copolymer consists essentially of maleic and itaconic moieties. One particularly preferred class of copolymer salts are the SFP AVAIL® and Nutrisphere-N® products described previously, which are formed using substantially equimolar amounts of maleic and itaconic moieties.
Most preferably, each of said partial salt copolymers has the generalized formula
<chemistry id="CHEM-US-00001" num="00001"><img file="US9738565B2_D0001.tif" /></chemistry><br /> where some of said X cations are H, and others of said X cations are Ca in the case of the partial calcium salt copolymer and ammonium in the case of the partial ammonium salt copolymer, and p ranges from about 10-50.
The partial calcium salt copolymer initially (i.e., before mixing with the partial ammonium salt copolymer) should have a pH of from about 1-4; likewise, the partial ammonium salt copolymer initially should have a pH of from about 1-4. The most preferred initial pH level for both salt copolymers should be about 1-2.
The complete treating materials should preferably contain at least about 30-60% by weight of total copolymer solids derived from both of the partial salt copolymers (more preferably from about 35-50% by weight solids), and from about 40-70% by weight water (most preferably from about 50-65% water). However, the treating materials may also include other ingredients apart from the two partial salt copolymers and water, such as pH adjustment agents, buffering agents, preservatives, and emulsifiers. Any such other ingredients are preferably used at a minor level, e.g., from about 1-10% by weight. The pH of the complete treating materials should be acid, preferably from about 1-5, more preferably from about 2-4.
Preferably, the calcium partial salt copolymer solids should be present in the complete treating materials in an amount greater than the amount of the ammonium partial salt copolymer solids therein. That is, taking the total weight of both copolymer salt solids as 100% by weight, the calcium partial salt copolymer solids should be present at a level of from about 50-80% by weight (more preferably from about 55-75% by weight, and most preferably from about 60-65% by weight), and the ammonium partial salt copolymer solids should be present at a level of from about 20-50% by weight (more preferably from about 25-45% by weight, and most preferably from about 35-40% by weight).
The single most preferred formulation useful in the context of the invention is the previously described MTM® product.
The Preferred Uses of the Treating Materials
Application of the dual partial salt copolymer materials of the invention is quite straightforward. In the case of manure collection pits, the material need only be poured onto the top of the manure and will quite readily spread and diffuse throughout the mass of the manure to promptly reduce the amount of gaseous nitrogen generated and maintained within the confinement facility. In the case of dairy or poultry barns having floor structures with litter and manure atop or mixed with the litter, the treating material is advantageously sprayed onto the top of the litter-manure mixture, with or without mixing. Here again, the action of the treating material is quite prompt and long-lasting.
Generally, the treating mixtures are used at a level of from about 0.005-3 gallons of the material per ton of manure, more preferably from about 0.01-2.5 gallons/ton, still more preferably from about 0.02-1 gallon per ton, and most preferably from about 0.03-0.035 gallon per ton.
Almost immediately upon application of the treating material to the manure, the amount of gaseous ammonia within the confinement facility is perceptibly lowered, and such reduction persists for a considerable time. Generally, the prevailing amount of gaseous ammonia should be reduced by at least about 50% (more preferably at least about 60%) within 24 hours after application. A single treatment also preferably serves to maintain at least about a 30% gaseous ammonia reduction (more preferably at least about 40%) for at least about 14 days (more preferably at least about 21 days).
EXAMPLES
The following examples describe preferred methods in accordance with the invention. It should be understood, however, that these examples are provided by way of illustration only, and nothing therein should be considered a limitation upon the overall scope of the invention.
In these examples, the “treatment” was the preferred MTM® treating agent described above. The ammonia measurements were made using meters having an average data point entry every 10 seconds, and the time in minutes listed in the tables refers to the total time of each reading at multiple points. For example, a reading of “15 mins., 2 points” means that there were two separate measurements at different points, each measurement being over a period of 7.5 minutes. The results of the multiple-point measurements were then averaged to give the reported ammonia levels.
In certain of the examples, the amount of treatment agent is recited as “ounces per acre.” This is based upon the manufacturer's recommendation of usage, according to the following equation: <br />(amount of manure in gallons)/(number of acres to be fertilized with the treated manure)×(18 oz. of MTM®)/(128 oz./gallons)=gallons of MTM® to add to the manure
Example 1
In this test, a poultry layer house was treated having approximately 300 tons of litter in the house basement. The litter was treated with 25 gallons of the preferred liquid mixture, which was incorporated into the litter using a composting tractor with a sprayer mounted on the front and supporting a rear tank containing the mixture diluted with 75 gallons of water. Gaseous ammonia levels were determined prior to application of the treatment mixture on Days 1 and 3, on the day of treatment (Day 4), and thereafter on Days 5, 10, 11, and 12. Ammonia measurements were made at the exhaust fan and in the basement, with each measurement being taken three times and averaged. The following are the test results.
